In most modern hospitals, no one is allowed to enter the operating theatre without wearing a surgical face mask. The practice of wearing masks is believed to minimize the transmission of oro- and nasopharyngeal bacteria from operating theatre staff to patients' wounds, thereby decreasing the likelihood of postoperative surgical site infections. In this era of cost-restraints, shrinking hospital budgets, and evidence-based medicine, many health care professionals have begun to re-examine traditional infection control practices. Over the past decade, studies challenging the accepted dogma of surgical face mask usage have been published. Masks that function as protective barriers are another emerging issue. Due to a greater awareness of HIV and other blood-borne viruses, masks are taking on a greater role in protecting health care workers from potentially infectious blood and body fluids. The purpose of this review is to evaluate the latest evidence for and against routine use of surgical face masks in the operating theatre.
在大多数现代医院，任何人不戴外科口罩都不得进入手术室。人们认为戴口罩的做法可将手术室工作人员口腔和鼻咽部细菌传播给患者伤口的情况降至最低，从而降低术后手术部位感染的可能性。在这个成本受限、医院预算缩减且基于循证医学的时代，许多医护人员已开始重新审视传统的感染控制做法。在过去十年里，发表了一些对手术口罩使用的公认教条提出质疑的研究。作为防护屏障发挥作用的口罩是另一个新出现的问题。由于对艾滋病毒和其他血源病毒的认识提高，口罩在保护医护人员免受潜在感染性血液和体液侵害方面正发挥着更大的作用。本综述的目的是评估支持和反对在手术室常规使用外科口罩的最新证据。
